Air-tight sound-proof window

ABSTRACT

Disclosed is an air-tight sound-proof window which is composed of an external frame, an inner sash and an outer window frame, wherein hollow steel reinforced concrete and sound-absorbing materials are internally installed in the frame of the external frame, the inner sash and the outer sash, and then iron bars are drilled in the center of the head horizontal jamb and the bottom horizontal jamb in the external frame, and afterwards, hidden screen grooves are installed in the border, and then moveable spacers and telescopic tracks are also installed in between the head horizontal jamb and the bottom horizontal jamb so that the inner sash and the outer sash can slide leftward and rightward and the sashes can also simultaneously move inward in such a way that the sashes are completely coupled to the rubber bars encircled around the inner border of the external frame so as to achieve air tightness. Hence, the movement of the inner sash and the outer sash is achieved by means of the locking action of the handle set at different locations. Moreover, the moveable cover in the transparent part between the inner sash and the outer sash can be stuffed so as to achieve complete air tightness and sound insulation of the window when the window is closely locked.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to an air-tight sound-proof window, and in particular, to the air-tight sound-proof window in which the stress tolerance of sashes is increased, and complete air tightness and sound insulation can also be achieved with the implementation of several innovations such as telescopic tracks, moveable spacers and sectional locking structures at the left, the center, and the right when the window is locked.

2. Description of the Prior Art

In response to technological advancement and industrial and business progress, people's demand for quality of life gradually increases. However, noises also arise as a result of industrial and business progress. Moreover, higher buildings are built as time goes by. However, the higher the building, the higher the wind pressure to be supported by the sashes. Especially in regions of frequent typhoons, air tightness, water tightness and safety of the windows become even more important, thereby bringing about air-tight windows.

In general, there are three types of air-tight windows, namely, the fixed type, the casement type and the horizontal sliding type. Although the fixed type air-tight window can be completely air-tight, people cannot enjoy the wind naturally existing in the environment when this type of window is used. Hence, its uses are limited. On the other hand, the casement type air-tight window has to be pushed open outward whenever it is used so that it takes more spaces and is easily subject to damages when it is blown hard against by strong wind. In this way, it is also not suitable for high buildings. Hence, among the three window types, the horizontal sliding type air-tight window is mostly used nowadays.

The exterior of the horizontal sliding type air-tight window is aluminum extrusion type wherein an inner sash and an outer sash are installed. In order to facilitate the sliding of the inner sash in relation to the outer sash, there are a lot of air spaces inherent in its overall structure, resulting in sub-standard water insulation and sound insulation. As a result of this, manufacturers have invested a lot in R&D on this for years. For example, the Taiwanese Patent Publication No. 357824 entitled “Safety Door Locks And Sound-Proof Window Frames” relates to an improvement in the contact between the jamb and the window border; the Taiwanese Patent Publication No. 362691 entitled “Air-Tight Sound-Proof Window Structure” relates to an improvement of pulleys; the Taiwanese Patent Publication No. 368030 entitled “Air-Tight Sound-Proof Windows” relates to an improvement in which a pulley base is installed in the jamb so as to enable a panel to be installed in the pulley base; the Taiwanese Patent Publication No. 388449 entitled “Air-Tight Sound-Proof Window Structure” relates to an improvement in which rubber bars are installed in one side of the jamb and then steel balls and ball tracks are installed in the other side of the jamb to embed the jamb in steel balls and stuffing; the Taiwanese Patent Publication No. 400889 entitled “Frame Structure of Sound-Proof Window” relates to an improvement in which elastic axial elements are internally installed inside a groove located in the jamb of the frame. It is obvious from the above-mentioned patent applications that manufacturers primarily invest in the reduction of air spaces inherent in the windows by innovations including high-level and low-level water insulation, drainage improvement, additional installation of PC bars, additional installation of windscreens, a detachment-resistant design, an internally dismantled type, and aluminum extrusion-type precision improvement.

However, even if the conventional sound-proof window has been improved by the innovations disclosed by the above-mentioned patents, the following flaws are still inherent in the conventional sound-proof window so that they are to be overcome:

-   1. The inner sash and the outer sash slide in relation to one     another along the front fixed track and the rear fixed track. When     they slide, another half of the track will form a “transparent     part.” Although nowadays the “high-level and low-level” bottom jambs     are used to reduce the size of the transparent part and prevent     water entry, this is the major reason for windows failing to achieve     complete air tightness. -   2. The inner sash is a hollow aluminum extrusion-type frame wherein     there is air inside so that both the frame and the air become the     media of noise transmission. In this way, this hinders complete     sound isolation. -   3. Although the fixed type track provides a guide for sliding the     window, air spaces have to be reserved in the top, the bottom, the     front, the rear, the left, and the right of the inner sash and the     outer sash when installing the inner sash and the outer sash so as     to facilitate the sliding of one sash in relation to the other. In     this way, when the door keeper is used to tightly lock up the inner     sash and the outer sash, the inner sash and the outer sash cannot be     completely tightly sealed due to the limitations inherent in the     fixed type track. In spite of this, only a plurality of PC bars can     be used for reinforcing the sashes. -   4. The window is punched, mortised, and perforated by means of     upright jambs, and then embedded and locked up in the horizontal     jambs by screws. But this installation is loose and imprecise so     that the window so installed is not strong enough to be locked just     by screws. In this way, water easily leaks from different     directions. As the upright jambs have to be embedded in the     horizontal jambs, there may even be difference in the thickness     between the upright jambs and the horizontal jambs in the inner     sash. -   5. The stress tolerance of the hollow aluminum extrusion-type frame     is low; the frame is light and the pulley is located at a high     position; the track is shallow. Hence, the frame is easily uplifted     when a pulling force is improperly applied to the frame, thereby     causing the frame to be detached from the track and fall off. -   6. There are flaws inherent in the horizontal sliding screen     installed in the exterior of the window. They are, namely, easy     detachment from the track, hindrance of the visual field, damage to     the overall design and easiness to get dirty and damaged

In order to overcome the shortcomings inherent in the conventional sound-proof window described above, the present inventor has delved into this matter with long-time efforts and has come to the realization of the present invention.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an air-tight sound-proof window. The air-tight sound-proof window according to the present invention is an invention wherein a track for moving the window is a telescopic moveable design so that the inner sash and the outer sash can freely slide in relation to one another in different directions such as the left, the right, the front, and the rear. Moreover, when the sashes are closely locked, the inner sash and the outer sash can be completely coupled together so as to achieve complete air tightness and sound isolation.

The air-tight sound-proof window according to the present invention is an invention wherein a moveable cover is further installed in the top of the upper track and the lower track in the external frame. By means of the moveable cover, the transparent part can be stuffed so that the inner sash and the outer sash can be completely locked up. This is anther object of the present invention.

The air-tight sound-proof window according to the present invention is an invention wherein the frame of the inner sash is an aluminum frame which embeds in steel reinforced concrete and stuffed with sound-absorbing materials so as to reinforce the frame, achieve rust resistance and a better external appearance for this structure which is primarily based on steel reinforced concrete, and directly facilitate the formation of grooves from the aluminum materials. Hence, the cost of aluminum materials can thus be greatly reduced. This is another object of the present invention.

The air-tight sound-proof window according to the present invention is an invention wherein on the external frame, a jamb is installed in the exterior of the vertical jamb in relation to the inner sash and the outer sash so that this can add stability to the external frame, making it strong without any deformation in shape, prevent the sashes from being detached and prevent burglars from intruding, and moreover, the jamb can also be used as the fulcrum for applying force to pack the inner sash. This is another object of the present invention.

The air-tight sound-proof window according to the present invention is an invention wherein a hidden screen groove is installed in one side of the external frame so that the hidden screen groove can hold a hidden screen inside so as to adjust the extended area of the screen formed by pulling the inner sash with reference to the opening position of the inner sash. In this way, this will not affect the visual field outside the window when the window is closed, and moreover, this can also reduce the dirt and damage caused by exposing the window. This is another object of the present invention.

The air-tight sound-proof window according to the present invention is an invention wherein the upright jamb and the horizontal jamb of the inner sash are of equal thickness so that there is no difference between them when they are assembled. Moreover, the frames are all in the shape of square pipes so as to facilitate the application of force for packing. Only water-proof grooves should be reserved for the medial vertical jamb. Moreover, rubber bars are all installed in the external frame so that a plurality of PC bars and accessories are not required for the inner sash. This is another object of the present invention.

The air-tight sound-proof window according to the present invention is an invention wherein hollow steel reinforced concrete and gear packing are installed inside the external frame to facilitate the application of force for packing, and grooves are thus formed in the border located in the periphery of the frames so as to install air-tight foaming rubber bars, thereby effectively achieving packing for the locking structures at different locations when the inner sash and the outer sash move inward. This is another object of the present invention.

The air-tight sound-proof window according to the present invention is an invention wherein air-tight rubber bars are encircled around the interior of the external frame so that the inner sash and the outer sash can completely be coupled to the air-tight rubber bars so as to achieve air tightness and sound isolation when the inner sash and the outer sash move inward. This is another object of the present invention.

A more complete understanding of these and other features and advantages of the patent invention will become apparent from a careful consideration of the following detailed description of certain embodiments illustrated in the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, the air-tight sound-proof window of the present invention is composed of an external frame 1, an inner sash 2 and an outer sash 3; said external frame 1 extends to the building by means of the fixed iron legs 13 so that the external frame 1 is joined to the building; the inner sash 2 and the outer sash 3 are installed between the left jamb 11 and the right jamb 12; a layer A1, A2, and A3 are respectively installed in the exterior of the upright jamb between the inner sash 2 and the outer sash 3 and then are also respectively propelled by a side jamb locking structure 4 or a medial jamb locking structure 5; the telescopic track 6 (as shown in the rear diagram) is installed in the bottom of the inner sash 2 and the outer sash 3; their top can be separated by means of the moveable spacer set 7 (as shown in the rear diagram); a moveable cover 8 is also installed in its corresponding transparent part 18.

Referring to FIG. 2, it depicts the left jamb 11 and the right jamb 12 of the external frame 1 wherein the frame is of the aluminum extrusion-type and then hollow steel reinforced concrete and sound-proof materials are also installed inside so that this can add strength to the frame. In this way, the external aluminum frame so constructed possesses properties such as easiness in molding, rust resistance, and good external appearance. Moreover, the thickness of the aluminum materials can thus be greatly reduced, thereby greatly reducing the cost of the aluminum materials. Furthermore, cover 110, 120 are installed in the top of the external frame (as shown in FIG. 4.)

Slot 111, 121 are formed on the exterior of the external frame so as to fasten the iron legs 13, which are locked up in the steel reinforced concrete by screws after plugging the iron legs inside to achieve greater stability when the iron legs are joined to the building. A casement 112, 122 are formed in the center for installing the side jamb locking structure 4; a hidden screen groove 14 is formed in the front of the right jamb 12 to hold a roller-type screen 15. Moreover, the position in which a rubber bar 181 and 182 are respectively installed inside the left jamb 11 and the right jamb 12 that come into contact with the inner sash and the outer sash.

Referring to FIG. 3, a hollow steel reinforced concrete and sound-proof materials are installed in the head horizontal jamb 161 and the bottom horizontal jamb 162 in the external frame 1, and iron bars 160 are drilled in between (Please refer to FIG. 4.) A slot 1611 is formed in the bottom of the head horizontal jamb 161 so as to be installed in a moveable spacer set 7; a guide plate 1612 is formed at a suitable distance from the exterior of the slot 1611 as a guide guard-rail of the outer sash 3; a jamb 17 is separately installed in the exterior at the position in which the vertical jamb of the inner sash overlaps with the vertical jamb of the outer sash. Two sides of the jamb 17 extend inward to a lateral border 171, 172, which is installed in the layer A1, which can move forward and backward by means of the control of the medial jamb locking structure 5. The inside of the head vertical jamb 161 extends downward to the front in which a rubber groove 1613 is formed so as to hold a rubber bar 1614.

As shown in the figure, a track cardboard 1621 is formed in the top of the bottom horizontal jamb 162; a telescopic track (as shown in the rear diagram) is installed in the top of the track cardboard 1621. A water-guiding inclined plane 1622 (Please refer to FIG. 4) is formed in its section to enable the penetrated liquid to be drained via the water-guiding inclined plane 1622; an extended level board 1623 is formed in the front of the water-guiding inclined plane 1622 so as to install the jamb 17. The inside of the bottom horizontal jamb 162 extends upward to the front in which a rubber track 1624 is formed so as to hold the rubber bar 1625.

The frame of the inner sash 2 and the outer sash 3 is of the same structure so that only the inner sash is illustrated here. As shown in FIG. 5, the inner sash 2 is composed of the left upright jamb 21, the right upright jamb 22, the top horizontal jamb 23, and the bottom horizontal jamb 24 wherein the left vertical jamb 21 and the right vertical jamb 22 are covered with the top cover 211, 221 and the bottom cover 212 and 222 and are then trimmed after the aluminum extrusion-type frame has been stuffed with shorter hollow steel reinforced concrete 240 and sound-absorbing materials 250; whereas the head horizontal jamb 23 and the bottom horizontal jamb 24 are stuffed with shorter steel reinforced concrete and sound-absorbing materials and are then locked up by means of the guide plate 261, the water-proof cloth 262, the left upright jamb 21 and the right upright jamb 22 as a unit after having been centrally drilled with iron bars 231 and 241. As the frame is almost a solid structure and is composed of sound-proof materials, the sound absorption condition of the hollow so formed can be minimized and moreover, the maximum strength of the steel reinforced concrete can also be achieved. Then via holes are formed in the center of the left upright jamb 21 to install the medial jamb locking structure 5 wherein a mortised groove 27 is installed in the exterior of the medial jamb locking structure to be plugged in with an air-tight bar 28. Afterwards, pulleys 242 are installed in the bottom of the bottom horizontal jamb 24 for sliding on the telescopic track.

A side jamb locking structure 4 is respectively installed inside the casement (as shown in FIG. 1) of the left jamb 11 and the right jamb 12 in the external frame. As the overall structure of the two side jamb locking structures 4 is the same, and only their left sides differ from their right sides when they are installed, only the side jamb locking structure 4 of the right jamb 12 is illustrated here.

As illustrated in FIGS. 6, 7A, and 7B, a handle 41 is installed in the front of the side jamb locking structure 4. The shaft body 42 of the handle 41 deeply penetrates into the casement 112 and then a 45° slant gear 43 is installed on top of the shaft body 42 and is joined to a second 45° slant gear 44 at 90°. Afterwards, a main gear 45 is installed in the back of the axis 441 of the second 45° slant gear 44 and is then joined to the rack 46 at the bottom. Moreover, the rack 46 is formed on the top of a rack axis 461. The layer A2 (A3) is formed on one side of the rack axis 461 and is contained inside a sleeve 47 so that the layer A2 (A3) can move forward and backward inside the sleeve 47. Hence, the handle 41 can be used to interlock the layer A2 so as to push toward the inner sash 2.

A medial jamb locking structure 5 is locked up on the left upright jamb 21 of the inner sash and can penetrate into the right upright jamb 31 of the outer sash. As shown in FIGS. 8 and 9, the medial jamb locking structure 5 passes through the left upright jamb 21 of the inner sash and the right upright jamb 31 of the outer sash by means of a center shaft 51. A tip 511 is formed in the front of the center shaft 51 so as to join to the top seat 170 of the jamb 17. Moreover, threading 512 is formed in the front of the medial jamb locking structure so as to drill into the screw hole A11 of the layer A1 wherein a groove 513 is installed in the middle of the medial jamb locking structure to propel the linkage 9 whereas the back of the medial jamb locking structure penetrates into the handle head 52 and the conical spring 53 installed in the handle head 52 and then a handle 54 is also installed in the back of the medial jamb locking structure. A turning point 55 is installed in the junction at which the handle 54 crosses with the center shaft 51 so as to bend the handle 54 downward. The handle 54 can be turned to control the window-ward movement of the layer A1 and the left upright jamb 21 of the inner sash and the right upright jamb 31 of the outer sash are pressed against so as to push them to move inward.

As shown in FIGS. 10 and 11, the linkage 9 mentioned is installed inside the left upright jamb 21 of the inner sash in which the first crank 91 is encased inside the groove 513 of the center shaft 51, and then the first crank 91 is joined to the second crank 92, which is joined to the third crank 93, which is further joined to a crankshaft 94, which is then installed in a shaft holder 95. Another end of the crankshaft 94 is used to propel the bottom of the moveable cover 8 installed in the top and can be used to deflect the moveable cover 8 to another angle. Hence, as shown in FIG. 12, the linkage 9 can be interlocked and then turn the moveable cover 8 open when the handle is returned.

As shown in FIG. 13, the telescopic track 6 is installed in the track cardboard 1621 installed in the bottom horizontal jamb of the outer sash. Please refer to FIG. 14, which gives a view of an inner track 61, an outer track 62, the first tab strip 6A and the second tab strip 6B; the first tab strip 6A and the second tab strip 6B axially penetrate through the track cardboard 1621; a clip track 6A1 is formed in the bottom of the first tab strip 6A, and then the inner track 61 and the outer track 62 are made of stainless steel and moreover, the rail 63, 64 is installed in the top of the track so as to enable the pulleys to slide along. Furthermore, an inner left clip groove 611 and an inner right clip groove 612 are formed in the bottom of the inner track 61 and an inner right clip groove 612 is formed in the bottom of the outer track 62. A plurality of flat snap rings are installed between the inner right clip groove 612 of the inner right groove 612 and the clip groove 6A1 of the first tab strip, and between the inner left clip groove 611 of the inner groove and the outer right clip groove 621 of the outer groove whereas a plurality of via holes are formed in the bottom of the inner track 61 and the outer track 62 so as to allow several limit hooks to pass through.

The first limit hook 66 passes through the inner track 61 with one end fastened on the first tab strip 6A, and another end protruded at the exterior of the inner track 61 (at approximate 0 mm); the second limit hook 67 passes through the inner track 61 and the outer track 62 with one end fastened on the outer track 62 and another end protruded at a suitable distance (approximate 3 mm) from the inner track 61; the third limit hook 68 passes through the outer track 62 with one end fastened on the second tab strip 6B and another end protruded at a suitable distance (approximate 6 mm) inside the outer track 62. Hence, this limits the inward movement of the outer track 62 at a distance of 6 mm and the inward movement of the inner track 61 at a distance of approximate 3 mm. (For a better understanding, different limit hooks 66, 67, and 68 illustrated are located at different heights, and when they are actually installed, different hooks 66, 67, and 68 are fastened on the same plane to be embedded.)

As shown in FIG. 15, the moveable spacer set 7 in the slot of the head horizontal jamb in the external frame is installed. The moveable spacer set 7 includes a spacer 71, a first tab strip 72 and a second tab strip 73; the first tab strip 72 and the second tab strip 73 axially pass through the slot 1611; a clip slot 74 is formed in the bottom of the first tab strip 72, and moreover, the spacer 71 is slender in shape and located between the inner sash 2 and the outer sash 3. An inner clip slot 711 is formed in the bottom, and then a plurality of flat snap rings 75 are installed in between the inner clip slot 711 and the first slot 74, and afterwards, a plurality of via holes are formed in the bottom of the spacer 71 for several limit hooks 76 to pass through them.

After the limit hooks 76 pass through the spacer 71, one end is fastened on the first tab strip 72 whereas the other end is protruded and coupled to the exterior of the spacer 71.

The upward open limit hook structure not only prevents the snap rings installed from falling off, but also limits the position of the track when it rebounds. Moreover, by embedding the upside-down hook in the track or the spacer, the track or the spacer is coupled inside the external frame.

As shown in FIG. 13, the moveable cover 8 in the transparent part formed by the intersection of the outer sash 2 and the inner sash 3 is respectively installed in the head horizontal jamb 161 and the bottom horizontal jamb 162 of the external frame. The moveable cover 8 of the bottom horizontal jamb is illustrated here.

As illustrated in FIGS. 16A, 16B, 17A, 17B, and 17C, the design of the moveable cover 8 can completely seal off the transparent part 18. Its inside is stuffed with the steel board 80 to add strength to the structure. One end is the inclined plane 81 corresponding to the medial vertical jamb 21 of the inner sash. Foaming rubber bars 82 are installed in different planes and then fastened on the bottom horizontal jamb 162 of the outer sash. A plurality of accessory pulleys at 90° is installed in the front. Moreover, a return spring 841 is installed inside the accessory pulley 84 at the outermost. When the moveable cover 8 is lifted up, the return spring 841 enables the external pulley 84 to return to its original position so as to ensure that it comes into contact with the left vertical jamb. Furthermore, as shown in FIG. 18, relative to the moveable cover 8, a fixed block 86 is installed in one side of the outer sash so that it can maintain its water level when the moveable cover 8 is closed.

The torsion spring 83 as shown in FIGS. 19A, 19B, 20A, and 20B is locked up on the moveable cover 8 by means of the head jamb 831. Then the bottom jamb 832 is locked up on the top platform of the hollow steel reinforced concrete of the bottom horizontal jamb of the outer sash. Moreover, its bottom jamb forms at least a transposed hole 833, which is installed in a steel ball disc 834, and then a screw 835 passes through the steel ball disc 834 and the transposed hole 833; moreover, a plurality of steel balls 836 are also installed in the bottom of the steel ball disc 834 so as to press against the lower jamb 832. In this way, when the spring 83 moves, the steel ball 836 rolls, with the result that this does not affect the fastening of the screw.

Moreover, a groove 837 can be formed in the bottom jamb of the spring 83 so as to hold the steel balls 838 or rollers so that the bottom jamb 832 can successfully move. In this way, the moveable cover can move at a suitable distance and moreover, its rubber bars in the periphery can be completely packed.

A view of the above-mentioned air-tight sound-proof window when it is closed is illustrated in FIGS. 21A, 21B and 22. The moveable cover 8 is pressed down by the torsion spring 83. Then the moveable cover 8 is uplifted at 45° when its bottom is supported by the crank 94. Afterwards, the center shaft 51 passes through the via hole 30 of the right upright jamb of the outer sash relative to the via hole of the left upright jamb of the inner sash. Moreover, the moveable cover 8 is made to be at a level position by means of the fixed block 86 (as shown in FIG. 24.)

When the handle 54 is uplifted so as to keep it at a straight line with the center shaft 51 (as shown in FIG. 24), the moveable 8 regains its elasticity by means of the return spring so as to allow the linkage 9 that is connected to the center shaft 51 to move forward, whereas the center shaft 51 passes through the via hole of the outer sash in the front as a result of the rebounding force of the conical spring 53. When the front threading 512 of the center shaft is embedded in the screw hole of the layer A1, the moveable cover 8 is pressed down to the fixed block 86 till a level position is reached; when the handle 54 is turned, the layer A1 moves inward when the screw hole is propelled by the threading. Hence, when the entire layer A1 moves, the right upright jamb of the outer sash is first pushed to make the left upright jamb 21 of the inner sash be inward attached and then the outer sash 3 and the inner sash 2 are moved inward so as to allow them to be coupled to the rubber bars 1614, 1625, 181 and 182 in the inner border of the external frame, and the rubber bar 82 around the moveable cover 8.

When the left upright jamb 21 of the inner sash moves inward, the inclined plane of its left upright jamb comes into contact with the inclined plane of the moveable cover 8 so as to pack the moveable cover 8 to enable it to produce backward movement and leftward slanting pressure. The transposed hole 833 on the torsion spring allows the moveable cover 8 to move in a slanting direction and the rubber bars in the periphery of the moveable cover 8 to be packed.

Moreover, turn the handle 41 of the side jamb locking structure 4 inside the left upright and the right upright jamb of the external frame, interlock the slant gear 43, 44, and the main gear 45, and then propel the rack 46 and the layer A2 (A3) to simultaneously move inward and then press against both the right upright jamb 22 of the inner sash and the left upright jamb of the outer sash so as to make them move inward and couple to the jamb rubber bars 181 and 182 inside the outer sash.

When the outer sash 3 and the inner sash 2 are pushed toward the top by the layer A1, the flat snap ring 65 installed in the lower end of the telescopic track 6 and the flat snap ring 75 installed in the moveable spacer set 7 are pressed as shown in FIGS. 25 and 26. The outer track 62 of the telescopic track 6 moves inward and then moves inward simultaneously together with the inner track 61, and then, the spacer 71 moves inward together with the outer sash 3 as a result of the pressure created by the inward movement of the outer sash 3. As shown in the structure, the plane of the inner sash 2 and the plane of the outer sash 3 move inward.

The entire surface of the inner sash 2 and the outer sash 3 move inward. Not only the inner sash 2 and the outer sash 3 are coupled to the rubber bar inside the outer sash, but also the transparent part is stuffed so as to apply force to the outer sash 3 and be also coupled to the moveable cover 8 because the moveable cover 8 has been installed.

Before opening the air-tight window, the handle 41 of the side jamb locking structure 4 is turned upside down and interlocks to the gear 43 and 44, and the main gear 45, and then propel the rack 46 and the layer A2 (A3) to move outward so as to counteract the force exerted by the left upright jamb of the outer sash by the right upright jamb of the inner sash.

Then turn the handle 54 upside down and separate the screw hole A12 from the threading 512, extract the center shaft 51, and press down the conical spring 53 so as to allow the center shaft 51 to divert to the left upright jamb 21 of the inner sash 2 and then bend the handle 54. When the center shaft 51 diverts and moves, its groove 513 propels the linkage 9. Through the interlocking of the linkage 91, 92 and 93 and the crankshaft 94, the moveable cover 8 moving upward and downward is thus bent outward at a fixed angle (at an angle of approximate 45°) (as shown in FIG. 27.)

When the moveable cover 8 deflects backward at an angle of 45°, the edge of its cover separates from the inclined plane of the left upright jamb of the inner sash 2 so that no contact is made; when the inner sash 2 moves leftward, the inclined plane of the left upright jamb 21 gradually comes into contact with the accessory pulleys 84 (as shown in FIG. 28.) Continue to pull the inner sash leftward so that the accessory pulleys 84 will move in response to the changes of the inclined plane and turn it from an original angle at 45° to more than 90°. In this way, the entire accessory pulleys 84 are installed thereon. When the inner sash is pulled leftward, it acts on both the top horizontal jamb and the bottom horizontal jamb in the inner sash 2. When the torsion spring 83 is deflected at more than 90°, then force will be applied to both the top horizontal jamb and the bottom horizontal jamb in the inner sash 2 by means of the accessory pulleys 84, thereby assisting the telescopic track 6 in pushing the inner sash 2 and the outer sash 3 to a pre-adjusted position that limits the movement of the limit hook. Hence, it can be known that the torsion equipment of the moveable cover 8 becomes the major return force of the telescopic track 6. When the window is closed, the moveable cover covers the transparent part 18 by means of the torsion exerted by the torsion spring 83. In addition, in order to maintain the life of the rack, pack the rack suitably to make it not too tight or not loose, to make the rack be used conveniently and prevent young children's danger from opening it, the present invention even provides a further improvement of the handle of the lock.

As shown in FIG. 29, the center of a handle 100 is composed of a sleeve 101 that opens to one end. A first ratchet 102 is installed inside the sleeve so as to embed both the first ratchet 102 and a protrusion 102A on the top into a fixed hole of the sleeve. Moreover, a base 103A is installed in a shaft body 103, and then a mount 104 is installed at a suitable distance from the base 103A. A hole 104A is installed in the exterior of the mount 104 so as to enable the axis of the second ratchet 105 to be embedded. The bottom of the second ratchet 105 is supported by a spring 106 and its top is joined to the first ratchet 102 and allows the spring 106 to pass through the shaft body 103, the second ratchet 105 and the first ratchet 102 so as to lock them up on the sleeve by means of a screw 107.

As shown in FIG. 30, turn the handle when using it. Because the first ratchet 102 is joined to the second ratchet 105, the shaft body 103 can be interlocked so as to propel the gear to move. When turning the handle till a certain pressure is exerted, the two ratchets 102 and 105 become separated. This shows that this has achieved a state of packing (as shown in FIG. 31). From this, this can prevent the rack from being overly abraded. By adjusting the strength of the spring, this can control the maximum tightness required for packing.

Moreover, as shown in FIG. 32, a folded screen 99 can also be installed in the groove 14 of the external frame 1.

Moreover, as shown in FIG. 33, the linkage 9 mentioned above is installed in between the first crank 91 and the second crank 92 inside the left upright jamb of the inner sash and is then linked by a cross-linked connector 96. Hence, it can be seen that this can facilitate its relative movement.

It can be seen from the above-mentioned that the air-tight sound-proof window of the present invention possesses the following characteristics:

-   1. A jamb is installed in the exterior of the position at which the     medial upright jamb overlaps with the inner sash. This not only can     increase the stability of the external frame and make it strong     without any deformation in shape, but also can prevent the window     panes from falling off the window and burglars from intruding, and     as a fulcrum for applying force to the medial jamb between the inner     sash and the outer sash. -   2. The track is of the telescopic moveable design in which the inner     sash and the outer sash can freely move leftward, rightward, forward     and backward. When the window is locked, the inner track and the     outer track can also be attached inward and thus return to their     original position. -   3. The moveable cover can effectively stuff the transparent part so     as to make the inner sash and the outer sash completely locked. -   4. Steel reinforced concrete and sound-absorbing materials are     stuffed in the aluminum frame so that the overall strength     increases. In this way, this can prevent the frames from being     detached from the track and can also completely absorb noises.

From the above, the air-tight sound-proof window of the present invention can effectively provide air tightness and sound isolation, and can completely improve the flaws inherent in the conventional window frame. Moreover the invention has not yet been publicly disclosed and used. Hence, the present invention is deemed to comply with conditions for approvable patents stipulated by Patent Law. We sincerely hope that the present invention can be allowed for registration.
